Brief Introduction
PSP series is high precision programmable DC power supply new generation design adopted & Advanced technology, it has outstanding with-load transient response speed, super low ripple and high power density, also is support multi-units parallel connection working, different power models all use the same enclosure.
This series is ideal option for products research, qualification, manufacturing burn-in, medical filed, environment field, energy & electric field, ATE test and other filed need high-power DC power supply.
Features: High efficiency, power-saving, environmental and low emission. High reliability & stability Super low ripple @ 20mVrms Low noise @100mVp-p,20Hz~20MHz 1ms quick load response, ±0.75% fluctuation Quick load response: Meet requirement of quick load or current variance, load response time＜1ms, voltage fluctuation＜±0.75% Various control modes:
10-turn potentiometer
0~5V or 0~10V analog signal (isolated / non-isolated)
Programmable, different communication port: RS232, RS485, CAN, USB, GPIB, LAN etc.
Master-slave control Support multi-units parallel connection working, total power could be added up to 150KW Short/over heat/over voltage/lack phase protections Module assembly, easy for installation or maintenance. High power density: Power density is greatly improved by modular design; enclosure of 15KW unit is only 3U standard industry enclosure, which is more convenient for parallel operation & system configuration. Voltage compensation function: Connects to load directly to compensate voltage loss on load cable Technical Specifications
